"American environmental artist Andrea Polli’s Particle Falls, a real-time reactive light projection will be displayed on the façade of the Mona Bismarck American Center as part of ArtCop21, the official cultural program accompanying the 21st United Nations Conference on Climate Change (COP21). A large-scale public installation visible every evening from 6 PM, Particle Falls acts as a monitor, an alarm, and a thing of beauty simultaneously, allowing the public to see current levels of air pollution as a digitally generated lightshow that changes and adapts in real time. The installation will be accompanied by a round table discussion on the intersection of art, environment and activism." via http://www.artcop21.com/fr/events/andrea-pollis-particle-falls/
